Controller Features
1. System Pressure Switch
Turns the system air supply On and Off.
2. Mode Switch
Use Manual/Setup position to prime and test the valves
without running the press.
In the Auto/Run position, the system will spray lubricant
when the press begins stamping.
Press air solenoid must be properly installed to allow
the MicroCoat System to run in Auto/Run mode (refer to
pages 18–19).
3. Tank Air Pressure
Regulates air pressure in the lubricant reservoir. For
most lubricants, 1.03bar (15psi) is a good start.
Minimum setting is 0.83bar (12psi).
4. Nozzle Air
Regulates nozzle air pressure.
Average setting is 0.55 to 0.83bar (8 to 12psi). Higher
pressure provides finer spray.
5. Flow Controls
Provide independent flow control of the lubricant to
each spray valve. Each blue ring on the stem coming
out of the middle of the knob indicates one complete
revolution.
Turn counterclockwise to increase flow.

6. Low Pressure Switch
Registers low fluid pressure. Connects with low level
switch for press protection.
Must be wired to the press Emergency Stop
Circuit to prevent the press from operating without
lubricant pressure (refer to page 22).
WARNING
7. Tank Air
Air from this port pressurizes the lubricant reservoir.
8. Nozzle Air
Air from this port is used to spray the lubricant.
9. Valve, control air
Air from this port controls the opening and closing
of the spray valves.
10. Fluid Outlet
Pressurized lubricant flows from these ports to the
spray valves.
11. Constant Air Input
The main air supply to the system should be a
minimum of 4.14bar (60psi).
12. Fluid Inlet
Lubricant from the tank reservoir enters the manifold
through this port.
13. Control Air Input from Solenoid
Activates the system when the press begins
stamping. Minimum 4.14bar (60psi) required.

Tank Reservoir Features
1. Low Level Switch
Prevents the system from operating without lubricant when
connected to the press Emergency Stop Circuit. Switch opens
when tank level is near empty.
2. Air Pressure Relief Valve
Automatically exhausts air if tank reservoir pressure exceeds
2.76bar (40psi). Also used to manually exhaust air pressure
before refilling the tank.
3. Fill Port Cap
Ported threads relieve any residual reservoir air pressure when
cap is loosened.
4. Drain Plug (not shown)
5. Lubricant Inline Filter
6. Bleed Valve
Valve releases air after filter replacement.
